TitleVANCOUVER Expedition (VANC)
AbstractWe mapped, using Seabeam, side-scan and magnetics, the broad area of the Incipient Rift at 2deg 40 min N and extending ~135 km east of the East Pacific Rise, to constrain the tectonic and magmatic history of the region and test the hypothesis that the geochemical variations along the Incipient Rift reflect sampling of different portions of the wider EPR melting regime. We discovered an apparent second propagating rift located at about 3deg north with a rift tip propagating into ~1 Ma old EPR crust. We performed 14 camera tows using the WHOI Camera Tow System; 53 dredges, 5 wax cores, and several dozen additional sampling sites with wax balls deployed by the camera.
